PATTERNS FOR MACROEVOLUTION

CORNELL NOTES TITLE (PAGE 87)

PAGE 87

PATTERNS FOR MACROEVOLUTION▸ Divergent evolution

▸ Convergent evolution

▸ Coevolution

▸ Punctuated equilibrium

▸ Adaptive radiation

▸Mass Extinction

PAGE 87

DIVERGENT EVOLUTION▸ Formation of new and different species from a

common ancestor

PAGE 87

CONVERGENT EVOLUTION▸ Evolution of similar features from DIFFERENT

ancestors

PAGE 87

COEVOLUTION▸ Two (or more) species affect each other’s

evolution

PAGE 87

PUNCTUATED EQUILIBRIUM▸ Rare and rapid speciation, followed by little to

no evolutionary change, and so forth…

PAGE 87

ADAPTIVE RADIATION▸ Common ancestor evolves into different

species, each adapted to a different environment

PAGE 87

MASS EXTINCTION▸ Extinction of a large number of species in a

short amount of time

▸ Due to catastrophic global event or rapid environmental change
